Hauv computer science, qhov tseem ceeb ntawm kab yog cov ntaub ntawv paub daws teeb uas zoo ib yam li cov kab ke ib txwm muaj lossis pawg cov ntaub ntawv uas txhua lub ntsiab lus tseem muaj "qhov tseem ceeb" cuam tshuam nrog nws. Nyob rau hauv ib qho tseem ceeb kab, ib qho tseem ceeb uas muaj qhov tseem ceeb yog ua ntej lub caij uas muaj qhov tseem ceeb tsawg.
Koj txhais li cas los ntawm qhov tseem ceeb?
Qhov tseem ceeb hauv kab hauv cov ntaub ntawv yog qhov txuas ntxiv ntawm "ib txwm" kab. Nws yog hom ntaub ntawv paub daws teeb uas muaj ib pawg ntawm cov khoom. Nws zoo li cov kab "ib txwm" tshwj tsis yog tias cov ntsiab lus dequeuing ua raws li qhov tseem ceeb. Qhov kev txiav txim siab ua ntej dequeues cov khoom ua ntej uas muaj qhov tseem ceeb tshaj plaws.
Yuav ua li cas thiaj muaj qhov tseem ceeb?
Cov chav kawm siv Serializable, Iterable, Collection, Queue interfaces. Ob peb lub ntsiab lus tseem ceeb ntawm Priority Queue yog raws li nram no: PriorityQueue tsis tso cai null.
Dab tsi yog qhov tseem ceeb ntawm kab nrog piv txwv?
Qhov tseem ceeb queue txhawb tsuas yog cov ntsiab lus sib piv, uas txhais tau hais tias cov ntsiab lus tau teem rau hauv qhov nce los yog nqis los. Piv txwv li, piv txwv li, peb muaj qee qhov tseem ceeb xws li 1, 3, 4, 8, 14, 22 muab tso rau hauv qhov tseem ceeb ntawm kab nrog kev txiav txim rau qhov tseem ceeb yog los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj.
Yuav ua li cas hauv qhov tseem ceeb?
Qhov Ua Ntej Queue yog qhov txuas ntxiv ntawm kab nrog cov khoom nram qab no. Txhua yam khoom muaj qhov tseem ceeb cuam tshuam nrog nws. Ib qho tseem ceeb ntawm qhov tseem ceeb yog dequeued ua ntej ib qhoelement nrog tsawg qhov tseem ceeb. Yog tias ob lub ntsiab lus muaj qhov tseem ceeb tib yam, lawv tau txais kev pab raws li lawv qhov kev txiav txim hauv kab.
